inner margin to the apex ; outer branches elongate ovate, 

 about two-thirds the length of the inner, proximal half of 

 the outer margin ciliated, inner margin slightly ciliated 

 towards the distal end, apex and distal half of the outer 

 margin furnished with six setae, the second from the 

 inner part of the apex considerably longer than the others. 

 Caudal stylets rather shorter than broad and about one- 

 third the length of the last abdominal segment. 



Male. Antennules ten-jointed, fourth and sixth joints 

 very small. Swimming feet, with the exception of the 

 second pair, similar to those of the female. Inner 

 branches of the second pair two-jointed, second joint 

 bearing at the apex two strong and slightly curved spines, 

 the inner spine which is slightly longer than the outer 

 one, becomes distinctly bifid at the middle. The form of 

 the fifth pair of feet is somewhat similar to those of the 

 female, but smaller and furnished with fewer setae, the 

 inner branches have only two setae which are placed on 

 the apex, the outer branches have two setae on the outer 

 distal margin, the lower one being stout and spiniform, 

 two setae on the middle of the inner margin and one 

 seta on the apex. 



Habitat, 1 -mile off Spanish Head, Isle of Man, in 

 neritic material dredged from a depth of 16 fathoms. A 

 considerable number of specimens were obtained. 



Bemarks. — This species comes near Dactylopus tenui- 

 reviis, but can easily be distinguished from it by the 

 structure and proportional lengths of the antennules, the 

 length and armature of the inner branches of the first 

 feet, and also by the structure of the fifth feet.
